<b>Description:</b>
<p>

  
By default the crawler ONLY searches for links in documents of type "text/html".<br>Use this method to add one or more other content-types the crawler should check for links.<br><br>Example:<code>$crawler-&gt;addLinkSearchContentType("#text/css# i");<br>$crawler-&gt;addLinkSearchContentType("#text/xml# i");</code><br>These rules let the crawler search for links in HTML-, CSS- ans XML-documents.<br><br><b>Please note:</b> It is NOT recommended to let the crawler checkfor links in EVERY document-<br>type! This could slow down the crawling-process dramatically (e.g. if the crawler receives large<br>binary-files like images and tries to find links in them).
